INKING AND CLEANING DEVICE FOR STAMPING OR PRINTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 443,529, dated December 30, 1890.

Application filed August 23, 1890. Serial No. 362,856. (No model.)

.T 0 aZZ whom it may concern:

Be it known that I, MIoHAnL KENNEDY, a citizen of the United States, residing at the city of Philadelphia, in the county-o1 Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Inkmg and Cleaning Devices for Stamping or Printing Machines, of which the following is a specification.

My invention relates to power stamping or printing machines, and more especially to the construction and arrangement of the inking and type-cleaning devices thereof.

Heretofore power stamping or printing machines have been provided with reciprocating rollers for conveying ink or other suitable printing fluid or paste from an absorbent pad or other source of supply to the type, and although comparatively good results could be attained in practice, provided the rollers were permitted to revolve freely on their journals, yet it was difficult, owing to the accumulation of ink and dust, to insure the proper and regular action of the rollers, so that the latter in sliding across the machines, as well as the type, became worn and permitted the interstices of the type to become clogged with extraneous or foreign matter, thereby rendering the machines ineffectual and necessitating the stopping and thorough cleaning of the same for further use.

The principal objects of my present invention are, first, to dispense with inking-rollers, and consequently to obviate the above-mentioned defects and disadvantages, and, second, to provide an eflicient, durable, and simple device for cleaning the type and for conveyin g the ink to the same from an absorbent pad or other source of supply.

The nature and characteristic features of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which I Figure 1 is a front elevation of the stamping-machine having the front portion of the table thereof broken away to expose to view the inking and cleaning brush thereof. Fig. 2 is a top or plan view of Fig. 1. Fig. 3 is an elevation on the line 3 3 of Fig. 2, and Fig. 4 is a detached view showing a removable brush adapted to be adjustably attached or secured to the reciprocating carriage of a power stamping-machine.

In the drawings, a is a table for supporting the work.

I) is a polygonal wheel provided with types I) protruding through an aperture in the table and extending above the upper surface thereof.

b is a rock-shaft supported in suitable hangers attached to the lower surface of the table a and provided with an arm h a bifurcated arm Z2 and a cam 5 b is a link pivotally attached to the arm b and to a source of motion (not shown) for actuating the shaft 19 c is a platen supported by the frame-work a and adapted to press the material to be printed or stamped onto or against the type b. This platen c is actuated by means of the working-beam 0, link 0 and cam-bar 0 d is an absorbent pad protruding through a suitable aperture in the table a, and supported by a spring d, attached to one of the 7 5 rock-shaft hangers.

d is a screw engaging with the spring d and contacting with the table a in order to facilitate the adjustment of the pad with reference to the top of the table.

6 is a carriage sliding on ways 6 and c attached to the frame-work ct, and adapted to be reciprocated across the machine.

f is a sprocket-wheel keyed to the shaft f.

e is a chain passing around the pulleys e and sprocket-wheel f, and attached at the respective extremities thereof to the carriage e.

f is a wheel keyed to the shaft f and provided with a tooth f engaging with the bifurcated arm 12 to impart a reciprocating or oscillating motion to the sprocket-wheel f, chain 6 and carriage e.

g is a bifurcated finger for removing the material from beneath the platen after the former has been stamped or printed.

Having thus pointed out the principal features of one of the best known of the many types of power stamping or printing machines to which my invention is applicable, I now will proceed to describe the invention in con- ICO nection with such a machine, although it should be understood that the invention is applicable to various types of printing or power stamping machines provided with mechanism adapted to eifect printing or stamping and with the employment of an absorbent pad or other source of ink-supply and a reciprocating carriage.

Referring now more especially to Figs. 1, 2, and 3 of the drawings, h is a brush or equivalent device provided with arms h having slots 7:? formed therein. These arms h are secured to the carriage e by means of screws it passing through the slots It so thatthe brush may be adjusted, as required, with reference to the pad d and type Z).

A modified form of brush is illustrated in Fig. 4, in which the brush it is provided with a back, and is secured to the carriage e by means of screws engaging with the back of the brush and with a portion of the carriage 6, so that the brush may be easily adjusted laterally with relation to the type and may be removed from the machine, if required.

111 use the carriage c is reciprocated transversely of the machine, and the brush it, after contacting with and absorbing the ink from the pad (1, travels beneath the platen and toward the rightin the drawings and returns toward the left to the starting-point, thereby conveying the ink from the pad to the type and brushing or cleaning the latter. The material to be printed or stamped is then placed above the type, and the descending platen causes the former to be printed or stamped in the usual manner.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a printing or stamping machine, of a source of ink-supply, a platen, a reciprocating carriage, a brush connected with said carriage, and type mounted in said machine, substantially as and for the purposes set forth.

2. The combination, in a printing or stamping machine, of a source of ink-supply, a platen, a carriage, a brush adjustably conneeted with said carriage, and type mounted in said machine, substantially as and for the purposes set forth.

In witness whereof I have hereunto set my signature in the presence of two subscribing witnesses.

MICHAEL KENNEDY.
